Definitions

  • the invention falls within the field of kitchen appliances and in particular refers to a cooktop consisting of a base and a heating coating.
  • the cooktops known today consist of a base in glass- ceramic material and heating elements placed underneath the base.
  • the cooktops made of glass-ceramic material have excellent mechanical features and thermal conduction which is strongly directional: excellent in the direction orthogonal to the cooktop and poor in the direction parallel to the cooktop.
  • the heating elements, placed under the glass-ceramic base, operate through two principles: magnetic induction and radiant heat.
  • electromagnetic induction requires the use of ad hoc pots with a base made of a material capable of coupling electromagnetically with the coil field of the heating element.
  • the heating occurs by radiant heat through conductive spirals of the heating element, penetrated by electric current, which radiate heat to the base, from the lower surface to the upper surface of the glass-ceramic cooktop.
  • the object of the present invention is to create a conduction-heated cooktop that overcomes the drawbacks mentioned above with reference to the prior art, and in particular that ensures excellent performance, while maintaining great simplicity of production.
  • a cooktop comprises a base having an upper surface, on the side intended to support cooking containers such as pots, pans and the like, or food to be cooked directly, and, on the other side, a lower surface and an electrically conductive coating applied to the lower surface of the base.
  • the base is flat, in the form of a plate, for example square, circular or polygonal.
  • the base is made of a thermal conductive material, e.g. glass-ceramic.
  • Said coating is obtained by the application of a paint, applied to the entire surface or, alternatively, to regions thereof.
  • the coating is operationally connected to an electric power supply, for example through a distribution grid that distributes the current to multiple points on the coating in order to obtain a homogeneous distribution of current or a concentration in predefined areas, in a controlled manner.
  • the electric power supply is provided through components such as wires, ribbons, strips, films and the like.
  • the electrical supply of the coating is either direct current, e.g. 12 V or 24 V, or alternating current, e.g. 220 V / 50 Hz.
  • the coating When the coating is supplied with electric current, the coating is heated by the Joule effect and thus the upper surface of the base is heated by conduction.
  • the upper surface of the cooktop is heated very evenly, due to the surface distribution of the coating. Even in the case wherein the coating is applied only to regions of the lower surface of the base, for example m the shape of a disc or a ring, the heating of such regions is uniform.
  • the paint for obtaining the coating preferably comprises silicone or polyester-silicone or epoxy- silicone resin or combinations thereof.
  • the solvent used is water or organic solvent .
  • the paint is loaded with electrically conductive particles.
  • These conductive particles are preferably carbon allotropes, such as single-wall or multi-wall carbon nanotubes, graphene, or copper or nickel metallic particles, or combinations of copper and nickel.
  • said conductive particles provide for a mixture of the aforesaid carbon allotropes and metallic particles, e.g. carbon nanotubes and copper and/or nickel particles.
  • the paint contains dispersants, such as surfactants, gum arabic, serinol pyrrole, etc., suitable to prevent or limit the agglomeration of the particles.
  • dispersants such as surfactants, gum arabic, serinol pyrrole, etc.
  • the conductive particles are mechanically dispersed using ultrasound or a paddle mixing system.
  • the paint contains carbon nanotubes in an amount of 0.1% - 20% by weight, and, in any case, in such quantity as to allow temperatures above 300°C, usually 340-350°C, to be reached, necessary to obtain a cooktop.
  • the quantity of nanotubes is such that the cooking surface takes on a black color.
  • the percentage of conductive particles in the paint is between 0.1% and 40% by weight.
  • the paint may be applied by roller, spray, glazing, silkscreen printing, pad printing or immersion.
  • the paint is then heat-treated, e.g. at 250°C for 10 minutes, to obtain the final coating.
  • the thickness of the coating after firing is between 1 ⁇ and 200 ⁇ .
  • the entire coating or portions of it are made separately from the base of the cooktop in the form of a sheath or flexible film or in the form of a rigid plate then applied to the base of the cooktop.
  • the electrical surface conductivity of the paint is between 5 ⁇ /sq and 1000 ⁇ /sq.
  • Example 1 A conductive silicone paint loaded with carbon nanotubes was applied by roller to the lower face of a glass-ceramic base of a cooktop. The content of carbon nanotubes in the paint is 15%. The paint was then fired for 10 minutes at 250°C in air. The resulting coating was then electrically connected via a copper grid to a 220 V / 50 Hz AC power supply. After a few minutes, the top surface of the base reached a temperature of 400°C and was maintained there for 60 minutes.
  • a conductive silicone paint with 5% multi-wall carbon nanotubes and 10% copper metallic particles was applied with a roller to the lower face of the glass- ceramic base of a cooktop. The paint was then fired for 10 minutes at 250°C in air. The resulting coating was then electrically connected via a copper grid to a 220 V / 50 Hz AC power supply. After a few minutes, the top surface of the base reached a temperature of 400°C and was kept there for 60 minutes.
  • the cooktop according to the present invention overcomes the drawbacks of the solutions of the prior art, as it allows a very homogeneous distribution of heat on the lower surface, improving the performance of the device. [0037] At the same time, the cooktop is simple and economical to make, because the paint does not comprise rare or hard-to-find components.
